Title: Filling a 16x16 tile randomly with 5 colors
Post by: Cherno on February 28, 2016, 06:15:11 pm
As the title says. I'd like to create a floor tile where the pixels are randomly filled with one of 5 different colors (gradient). I use Photoshop and have experimented with the Noise filter, but the I never manage to limit the result to 5 (or any arbitary number) of colors.

posterize layers would help you with that, i believe

I thought so too, but the posterize image option acts weird; The levels that can be set result in far fewer actual levels in the image.

Generate your noise in RGB mode, then set your image to Indexed mode with the palette size limited to whatever number of colours you want. That will reduce the colour count to that number. Then, you can customise the colours by changing the palette, or by going back to RGB mode and filling in the pixels with arbitrary colours with the Paint Bucket with 0 tolerance and Contiguous turned off.
